possibly. but try running 'ngctl list' in the jail to list all the
nodes it can see there.
as well as ifconfig
there might be an order dependency:
try this:
reboot with no netgraph nodes loaded.
make the jail
move vr0 to teh jail using ifconfig
kldload ng_ether
kldload ng_pppoe
(in the jail) run ngctl list
(in the jail) run ifconfig
and see if the result is different
if so then the trick would be to have the interfsce alreday in
the right jail when the ng_ether nodes are created.
if you do it the other way around it is possible that moving
theinterfaces to a new jail doesn't move the netgraph nodes
associated, leaving them behind in the old jail.

it should not be if you are running in a jail as the jail is inherited
by ifconfig.
